SPECIFICATiON forming art of Letters Patent No. 632,202, dated August29, 1899.

Application filed December 22,1898 Serial No. 700,023. (No model.)

To tZZ whom, it puny concern:

Be it known that we, HENRY PHILLIPS and VV ILL IAM HUNT, citizens of theUnited States, residingat Ottumwa, in the county of WVapello and Stateof Iowa, have invented certain new and useful Improvements inOar-Loaders; and we do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

Our invention relates to certain. new and useful improvements incar-loaders, and particularly in that type shown and described inLetters Patent granted to us November 3, 1896, No. 570,880.

In the patent referred to we have shown and described a hopper forreceiving coal from an ordinary chute and said hopper arranged in fixedrelation upon a secondary supporting frame or table, the latter capableof revoluble and reciprocating movement on a pedestal secured to the endof a pri mary longitudinallymovable frame.

One of the objects of our present invention contemplates dispensing withthe secondary frame mounted upon the pedestal and intermediate of thehopper and the primary frame and to provide for the support of alongitudinally and revolubly movable hopper directly upon the pedestal,thus reducing the weight and cost of the machine and at the same timesimplifying the manufacture.

Another object of our invention is to dispense with the foldingsides ofthe hopper and end-gate, as shown and described in the Letters Patentreferred to, and to so construct the sides of the improved hopper thatthey v shall be immovably secured in position, and also so constructingthe end-gate or pusher that it shall be all one rigid structure, thusnot only simplifying the construction of the hopper sides and end-gateor pusher, but at the same time materially adding to the strength of thesame.

Another object in view of our present invention is to dispense with theseries of stopholes employed to arrest the hopper at different points inits longitudinal progress and to so construct a combined table andhopper that it shall have a reciprocating movement about equal to itslength and with stop or locking mechanism to automatically arrest andhold and also release the table-hopper at each end after it has reachedits limit of movement.

Our present invention has as a further object to so locate the engineand the means of conveying power therefrom to the table-hopper andend-gate or pusher that the power will be utilized to the bestadvantage.

Another object had in view by our invention is to so construct andarrange the endgate or pusher, hopper-bottom, and traveling chain thatthe chain in its travel shall always be out of contact with the coallying upon the bottom of the hopper and that the endgate or pusher shallbe duly guided and held to its work.

Another object of our invention is to dispense with that portion of thepower-transmitting chain which in the patent referred to travelslongitudinally With the frame of the machine and to the center of thepedestal and to substitute therefor a rigid shaft and shaft rotatingmechanism, whereby the chain-wheel beneath the hopper is revolved andthrough it and the medium of a hopperchain the end-gate or pusher isreciprocated and the hopper likewise is automatically and at will movedin either direction longitudinally, as will be hereinafter more fullydescribed.

A further object of our invention is to provide an automatic locking andunlocking device for regulating the movements of the table-hopper to theend that when the end-gate or pusher is in motion delivering the coalthe table-hopper will be held at rest, and when the end-gate or pusherhas reached the limit of its travel in either direction it willautomatically unlock the table-hopper, thus instantly transferring thepower from the endgate or pusher to the table-hopper and greatlyincreasing the working capacity.

With these ends and objects in view our invention consists in thepeculiar features of construction and arrangement hereinafter more fullyset forth and claimed.

In order that those skilled in the art to which our invention appertainsmay know how to make and use the same, we will proceed to describe theconstruction and operation of our improved car-loader, referring byletters and numerals to the accompanying drawings, in which Figure 1 isan end elevation of our improved machine in its relation to a car andshowing the machine in the act of delivering a load to one end of thecar, the side of the latter being broken away to show more clearly therelation of the loader with the car. Fig. 2 is a side elevation of themachine and an end elevation of the car, the latter being broken away toshow the machine within the car receiving coal from an ordinary chutefrom the opposite side of the car-track and at the same time showing sofar as the loader is concerned its working position within the car. Fig.3 is a partial plan view showing in relief the powertransmitting shaftand the table-hopper. Fig. 3 is a detail side View of the locking-boltand operating-lever and connections by means of which the hopper isautomatically locked and released.

Similar letters and numerals of reference denote like parts in theseveral figures of the drawings.

A represents a suitable foundation, preferably of stone, built near theside of the tracks B.

C O are metal abntments or stands formed with bases D and strengthenedby cross-bars E, and upon the stands O are arranged track wheels orrollers F in suitable boxes or bearings G.

I I are I-beams constituting the main frame of the machine, and they aresuitably tied and braced in parallelism and have secured to the uppersurfaces a hood J, which arches and protects the engine K, which, asshown, is located. upon a suitable bed on the foundation A between thestands 0 O. A steam-cylinder L is mounted upon and secured to bracketsor supports L, (see Fig. 1,) bolted to the stands 0 and connected bysuitable and ordinary Valves, so that steam may be admitted andexhausted from each side of a head on an ordinary piston, the stem L ofwhich is connected to a lug or arm M at the rear end of the I-beamframeI. (See Figs. 1 and 3.) The I-beams I rest upon the wheels orrollers F and travel longitudinally thereon and are held againstvertical vibration by antifriction-wheels N. As steam is admitted atopposite sides of the piston-head the I-beam frame I will becorrespondingly moved in one or the other direction in an obviousmanner. The front end of the I-beam frame is rigidly secured and heldtogether by a metal base 0, (see Fig. 5,) with a circumferentialball-race near the top to receive antifriction-balls P. A frame or crownQ, having a disk bottom R secured thereto by screw-bolts S, confines theballs P in their race and is adapted to revolve upon the pedestal O andkeep the crown and table-hopper from tipping from position in an obviousmanner. The crown Q is formed with two parallel supports T, having lugs1 2 3, the end lugs 1 and 3 constituting bearings for rollers U, (seeFig. 1,) upon which rest curved lateral flanges 4 on the sides of thetable-hopper V, thus enabling the table-hopper to freely movelongitudinally in either direction, as hereinafter described. Thesupport T nearest to the front of the machine is provided with two shorteyebolts 5, secured in place by nuts 6, and to these eyebolts aresecured one end of coil-springs 7. (Shown on enlarged scale at Fig. 22and hereinafter more fully described.) The lug 2 on the front support Tis perforated with a square hole 8, through which recip'rocates thesquare end of a stop or locking pin 9, (shown on enlarged scale at Fig.18,) which automatically locks and releases the table-hopper as itisreciprocated upon the crown Q, as hereinafter described.

W is a bolt operated by a lever X and passing through a guide-lug intothe wall of the crown Q and is designed to lock the latter againstrotation in any given axial relation to the frame I.

The locking-pin 9 (shown at Fig. 18) is square at that portion whichpasses through the lug 2 (see Figs. 2, 3", 4, and 5) and round at theouter portion and passes centrally through a hub 16 at the lower end ofa lever 11 and is secured therein by an ordinary cotter-pin 12. Theinterior disk face of this hub is formed with two V-shaped recesses 13to receive the arrow-shaped ends 1% of two short bolts 15, (see Figs. 20and 23,) the stems of which are cylindrical and are located withindiametric recesses c c, Fig. 5,in the lug 2 on the crown Q. Between thecotter-pin l2 and the face of the hub 16 on the lever 11 is confined aplate 10, (see Fig. 21,) having diametric cars 17, which are perforatedfor connection with one end of the coilsprings 7, the opposite ends ofwhich are connected with the eyebolts 5 on the table-hopper support T,said springs acting to hold the lever-hub 16 toward the lug 2, andconsequently by reason of the annular shoulderon the locking-pin 9 thelatter is forced into its recess or stop-holes near each end of the sideof the hopper to lock the same in position, but when the lever 11 isvibrated upon the cylindrical portion of the locking-pin 9 thearrow-shaped heads 14 of the short bolts 15, contacting with theV-shaped recesses in the disk face of the leveahub 10, forces the latteroutward, and consequently the locking-pin 9 is withdrawn from its recessin the side of the hopper, so that the latter is free to be movedlongitudinally in to bring the opposite end of the hopper into positionto be locked by the locking-pin 9, it being understood that there is alocking recess or hole in the side of the hopper near each end thereof.The vibration of the lever and the withdrawal of the locking-pin 9 areautomatically effected through the medium of a chain 18, one end ofwhich is secured to the free end of lever 11 and the opposite end to theend-gate or pusher, hereinafter described, and arranged within thehopper, the length of the chain 18 beingpredeterminedl y such that justbefore the endgate or pusher reaches the limit of its longitudinalmovement in either direction it will pull upon the chain, vibrate thelever 11, and cause the locking-pin to be withdrawn from its recess inthe side of the hopper V, so that the latter, as will be presentlydescribed, will be free to be moved longitudinally in an oppositedirection to that occupied by it when the locking-pin is released, andwhenit has reached the limitof such movement, the chain being slack, thecoil-springs 7, pulling upon the hub of lever 11, will cause the'latterto return to its normal position, and consequently the locking-pin willenter itsrecess in the side of the hopper and lock the same againstmovement until the end gate or pusher reaches its limit of movement inan opposite direction to that already described.

The hopper V is made of steel plate and has a curved bottom or table, asclearly shown at Figs. 1, 2, 4, and 7, and consequently during itstravel it moves in a correspondinglycurved direct-ion, hence presentingitself always in the lowest posit-ion at the locality it receives coalfrom the coal-chute, and the point of delivery from the hopper being thehighest point of its movement, and consequently the coal is piled higherin the ends of the car than would be the case if the path of movement ofthe hopper were in a horizontal line.

On the upper surface of the bottom of the hopper are riveted twoZ-shaped bars 19, as clearly shown at Fig. 0, and they are so locatedwith reference'to each other as to provide a longitudinal slot, throughwhich the draw-bar of the end-gate passes and by which it is guided. Thechain which operates the end-gate or pusher is connected to the lowerpart of the d raw-bar and travels in the lower portion of the slot andupon the upper surface of the hopper-bottom, thus being prac ticallywithin a housing. Y

To each end of the bot-tom of the hopper bars 20 are riveted, eachformed with a series of horizontal bolt-holes, in which are locatedbolts 21, which pass through bolt-holes in secondary bars 22, theouterends of which constitute bearings for the axle or hub of chain-idiers23, as clearlyshown on enlarged scale at Figs. 8, 9, 10, and 11. Theboltholes through the inside bars 22 are greater in number and closertogether than the holes in the outer bars 20 in order that a greaterrange of adjustment of the bars 20- and 22 relatively to each other maybe made to secure adjustment in turn of the idler chainwheels 23relatively to each other in order that any slack of the chain 24: may betaken up. The chain 24 is attached at. each end to vertical lugs on thelower part of the draw-bar. The draw-bar is composed of two parts. Theupper part A is represented at Figs. 12 and 13 and the lower part B atFigs. 14 and 15. The lower part is formed with three arms a a I), eachhaving key or wedge slots 0, and

the upper part A is constructed, as shown, with slots cl, through whichthe arms a a b on the lower part B pass. This upper part A of thedraw-bar is formed with a recess, as clearly shown at Fig. 13, in orderthat it may fit over the Z-plates centrally located on thehopper-bottom, and when the two parts A B have been securely connectedby suitable wedges or keys placed in the slots 0 the upper part A willrest upon the upper surface of the hopper-bottom and the lower part Bwill lie within the slot or housing formed by the parallel Z-bars 19.

The end-gate or pusher C (see Figs. 6, 7, and 7 is securelybolted to theupper part A of the draw-bar, and the ends of the operating-chain 24, ashereinbefore stated, are connected to the arms Ct at of the lower partB, as clearly shown at Fig. 14, so that the draft of the chain isapplied most advantageously for operating the end-gate or pusher O. Thechain 24 passes over the idlers 23 on the ends of the hoppers, thenceover guiding-idlers 25, mounted in bearings 26 in the bottom R of thecrown Q, (see Figs. 1, 4, 5, 6, and 7,) and thence around asprocket-wheel D, driven by the shaft E. This sprocket-wheel and itsconnection with the shaft E will be presently explained in detail; butfrom what has already been explained it will be seen that as the ends ofthe chain 24 are attached, as before stated, to the arms 0 c of thelower portion B drawbar of the end-gate or pusher C the rotation of thesprocket-wheel D in one or the other directions will accordingly pullthe end-gate or pusher longitudinally along the hopper and force thecoal in front of said pusher over the elevated end of the hopper andinto the end of the car, and, as before explained, when the end-gatereaches the limit of its longitudinal movement the chain 18 isstraightened and then vibrates the lever 11 and releases the locking-pin9 from its recess or hole in the hopper, and the latter is then free tobe moved longitudinally in the direction opposite to that it occupied asthe coal therein was pushed out by the action of the end-gate or pusher.This movement of the hopper is accomplished through the followinginstrumentalities: The end-gate or pusher having reached a stop at theend of the hopper, the continued movement of the chain in the samedirection which caused the movement of the end-gate necessarily pullsagainst that end of the hopper and draws the hopper bodily back in thedirection of the arrow at Fig. 1, so as to bring the extended orelevated end of the hopper back and over the sprocket-wheel. Vhile thehopper has been traveling in this reverse direction, coal is dumped fromthe chute G, Fig. 2, and the hopper is fully loaded again in front ofthe end-gate or pusher C, and the chain 18 having been slackened by themovement of the hopper the coil-springs 7, hereinbefore referred to,cause the lever on the locking-pin to be vibrated and the locking-pin toenter its recess or hole in the side of the hopper, and thus lock thelatter in its new or reverse position. i

The engine K (which is an ordinary reversible engine) is then reversedby the reversinglever H, and the sprocket-wheel D is rotated in acorrespondiugly-reversed direction, and the chain 24c then, in themanner already described, pulls the end-gate or pusher against the coalin the hopper and pushes it off into that end of the car opposite towhere the original load of thehopper was dumped, and when the end-gatereaches its limit of movement it again causes the locking-pin to releasethe hopper, and the continued rotation of the sprocket-wheel pulls(through the medium of chain 18) the hopper backward, as alreadydescribed, and itis loaded as before, and so on.

I will now proceed to describe the manner in which power and motion aregiven to the main driving-shaft E. This shaft E, as clearly shown atFig. 3, is square in cross-sectien, and the hub I of the main gear J isformed with a correspondingly-shaped axial hole to receive the shaft,and consequently fixed axial relation is established between the shaftand main gear. The hub of the main gear is su l'fieiently long each sideof the gear and is cylindrical to constitute a journal which rotates insuitable boxes or bearings I in cross-beams K of the main frame. Thefree or rear end of the shaft E is supported in any suitable support toprevent sagging or vibration of the same, and it is obvious that as themain frame I of the machine is moved longitudinally in either directionthe shaft E is free to move through the huh I of the main gear. Rotarymotion is imparted to the shaft from the engine K through the medium oftwo pitmen K, connected with wrist-pins on the wheels K secured to theopposite ends of a short shaft K rotating in suitable hangerbearingsbolted to the under sides of the cross-beams K, and keyed to the shaft Kis a pinion K meshing with the main gear J, and consequently as theshaft K" and pinion K are rotated in either direction the main gear Jand the shaft E will be rotated in one or the other direction.

When a car to be loaded is properly located on the track between thesupplying-chute G and the loading-machine, and the hopper of the machineis in one or the other of its extreme longitudinal positions and looked,as shown, for instance, at Fig. 1, and the 110pper is at an angle offorty-five degrees to the main frame as a result of the action of itshaving been previously removed from a car, or, if it is being initiallyworked, by having been turned by hand into such position, the main frameI is moved through the medium of the cylinder L and its pistonconnection with the frame toward the car, and until that end of thehopper which is immediately over the main frame passes the side of thecar and into the door the main shaft E is then rotated through themechanism already described to such an extent as will reciprocate thehopper a sufficient distance to bring the extended end inside thevertical plane of the side of the door, and then the main frame isadvanced so that the pedestal shall be central between the sides of thecar, and the hopper is at the same time swiveled orturned in Theparallelism with the sides of the car. hopper will then be in positionto receive a load from the chute G. frame and hopper from a car, it isobvious that a reversal of the procedurej ust described will produce thedesired result.

I will now proceed to describe the construction and arrangement of theparts by which connection is made between the front end of the mainshaft E and the sprocketwheel D and by means of which motion istransmitted to the sprocket-wheel D and at the same time permitting thesprocket-wheel to rotate at different angles with the shaft as becomesnecessary when the crown Q and table-hopper are turned to a properposition, as will be hereinafter described for entering or withdrawingfrom the car. Special reference is here made to Figs. 24, 25, 26, 27,and 28.

The sprocket-wheel is composed of two diskhalves g g, on one of whichare formed the sprocket-teeth, or the teeth may be formed on a centralring and the latter clamped between the disk-halves g g. The two partsof the sprocket-wheel are secured together after the sphere h on the endof shaft E has been properly located by screw-bolts 2', dulycountersunk, as shown at Fig. 25. The diskhalf g is formed with atubular hubj, which takes its bearing in a box 70, form ed with anddepending from the crown Q, as shown in dotted lines at Fig. 4.

The spherical head or end it of the shaft E is formed with acircumferential groove or key-slot I each side of the juncture with theshaft, and the said spherical head and shaft are keyed to thesprocket-wheel by means of two keys 172, (see Fig. 28,) the short shanksof which fit within the groove Z in the head h, while the enlarged headportion of the keys m fit within recesses n in the inner circumferenceof the disk-half g of the sprocket- Wheel, as clearly shown at Fig. 24.

From the construction and arrangement described it will be seen that thesprocketwheel D is rotated by the driving-shaft E and that the former ispermitted to move at an angle to the shaft each side of the plane of theshaft E when the crown Q is rotated, as hereinbefore explained, topermit the hopper to enter and withdraw from the car.
